Abstract :
The economic feasibility of using SONET self-healing-ring (SHR) architecture in survivable interoffice fiber networks is studied. The model used is discussed, and the selection criterion for the candidate area in this study, the SHR cost model, the hubbing network cost model, the network survivability measure, and the network growth model are described. Results of two case studies based on a metropolitan local access and transport area (LATA) network are discussed. One involves a single- and the other a dual-homing interoffice network. Sensitivity analysis and network impact results are highlighted.<>
